水平定向钻进铺设管线的测量技术

Survey Technologies for Pipe and Cable Installation with Horizontal Directional Drilling

对于安全优质水平定向钻进铺设管线来说 ,测量技术至关重要。介绍了施工前对已有地下管线和土层的探测、钻进时对钻头的跟踪和导航、以及铺设管线前后的测量问题 ,还介绍了测量仪器的工作原理。

Survey technologies are very important to a safe and successful laying pipelines with horizontal directional drilling. This paper is involved with knowledge about location of existing utilities and exploration for soil layers before construction, tracking and navigation for the drill head during drilling, and survey of pipelines in pre and post installation stages. Work principles, basic performances and application ranges of survey instruments are also described.
